Abstract
The utility model discloses a compact four-core composite cable with a pilot core pair. The cable comprises a cable core. Three fan-shaped phase cores and a wrapping tape layer winding around the phase cores are intertwisted to form the cable core, which is wrapped by a core layer wrapped by an extruded outer sheath. The core layer is formed by a plurality of earth cores and at least one pilot core pair parallelly distributed around the cable core concentrically. The cable is low in signal interference and can transmit electric power and control signals at the same time. The wire arrangement is more reasonable and tighter. The cable is compact in structure, small in external diameter, easy to process, and convenient for construction.
Description
Technical field
The utility model belongs to electric wire field, particularly a kind of with controlling the right compact four-core composite cable of core.
Background technology
Along with the develop rapidly of the universal and information industry of computer technology, intelligent residential areaization has become the development trend of modern architecture, by the comprehensive wiring system that formed by composite cable etc. the communication in intelligent construction, computer and various device and facility, include under certain conditions comprehensive wiring system in, be interconnected to form complete supporting entirety, to realize highly intelligentized requirement.
The four-core composite cable of the band control core of prior art, structure is stranded by controlling cable core and four circular cores that are extruded with insulation conventionally, or four segment conductor-cores are stranded rear stranded with control cable core.Quad core comprises fourth class core that four cross-sectional area of conductor are identical or three cross-sectional area of conductor are large, a 3+1 core that cross-sectional area of conductor is little.No matter be the stranded of which kind of form, core gap is larger, not only make cable roundness poor, and extrude and the process such as construction in easily loose, and core easily channels bit, conventionally add packing material stranded together, and skin need be tightened with band when stranded for this reason, after stranded or stranding, extrude again sheath.The four-core composite cable of this structure band control cable core, not only cable core poor stability, and material usage is large, has also increased cable weight and cost.As adopt four stranded segment conductor-core structures, although cable core stability improves, core is processed into sector structure, processes round core complexity, needs strict control segment angle and fan-shaped height, and easily occurs the phenomenons such as in uneven thickness, insulating barrier splits; Secondly, no matter be the four-core composite cable of the band control cable core of which kind of stranded form, lay configuration, increases actual core length, waste material, increase weight, and cable cost increases; Again, this structure also makes the outside diameter of cable larger, especially large specification cable, and large external diameter has not only increased manufacture, transport difficulty, and takies that to lay space large.Besides, the composite cable power core of structure is larger to the electromagnetic interference of control core conventionally.
Utility model content
The utility model is to overcome the shortcoming that prior art exists, and provides a kind of signal to disturb little, simultaneously transferring electric power and control signal, winding displacement more rationally, closely, compact conformation, external diameter is little, is easy to the right compact four-core composite cable of band control core of processing and convenient construction.
Described in the utility modelly a kind ofly comprise cable core with controlling core right compact four-core composite cable, cable core is by three fan-shaped phase cores and wrapped stranded the forming of belting layer outside phase core at center, the outer lapped wire sandwich layer of cable core, and cable core extrudes oversheath outward; Described core layer is by being arranged in one heart side by side some ground cores outside cable core and at least one pair of controls core to forming.
Further improve, the phase conductor that described phase core is made up of some monofilament and wrapped insulating barrier in phase conductor form.
Further improve, described control core is to controlling cores, wrappedly control the metal knitted screen outside cores and the thin sheath being extruded in outside metal knitted screen forms at 2 by 2 that directly drag.
Further improve, described ground core, control the highly equidistant gap arrangement of core equity or be covered with outside cable core.
The beneficial effects of the utility model are:
Described in the utility model a kind of with controlling the right compact four-core composite cable of core, transferring electric power and control signal simultaneously, and have mutually metal screen layer to shield, independent mutually, signal disturbs little; Phase core, core all directly drag, saved packing material and band, reduced the waste of material of stranded increase length, alleviated weight.Compared with prior art, winding displacement more rationally, closely, has reduced to lay space, easy construction.Ground core with control core to together with concentric being distributed on outside phase core, make the phase core of bearing electric power transfer be positioned at innermost layer, not only can play similar steel wire armoured effect, can play a very good protection to phase cable core, effectively alleviate and damaged by external force.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, execution mode of the present utility model is elaborated.
As shown in Figure 1, a kind ofly comprise cable core with controlling core right compact four-core composite cable, cable core is by three fan-shaped phase cores 1 and wrapped stranded the forming of belting layer 2 outside phase core 1 at center, the outer lapped wire sandwich layer 3 of cable core, and cable core extrudes oversheath 4 outward; Described core layer 3 is made up of 6 the 5 and 3 pairs of control cores of 10 ground cores that are arranged in one heart side by side outside cable core.
The fan-shaped phase conductor 8 that described phase core 1 is made up of some monofilament 7 and wrapped insulating barrier 9 in fan-shaped phase conductor 8 form.
Described control core is controlled cores 10, is wrappedly controlled the metal knitted screen 11 outside cores 10 and the thin sheath 12 being extruded in outside metal knitted screen 11 forms at 2 by directly drag 26.
Described ground core 5, control core to the equidistant gap arrangement of 6 equal altitudes or be covered with outside cable core.
The concrete application approach of the utility model is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvement, these improve and also should be considered as protection range of the present utility model.
